Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.

Propliopithecids vs. Parapithecids. Adapids and Omomyids. Dryopithecus and Oreopithecus. With the exception of Gigantopithecus, many students struggle to differentiate between the various fossil primates. So, let's write about them, have a little fun, and help embed them in our brains. Create an original comic or storyboard that illustrates one of the fossil primates. Unlike the Primate Profiles, this is NOT meant to be a research project! This is meant to be a study tool for you. You should build comics primarily, if not exclusively.
